Assembly instructions for the Depron Avro Lancaster - Docu-and-Info

Assembly instructions for the Depron Avro LancasterPlease read these instructions completely before commencing with your build.Depron is easy to work, but care should be taken when making the bends required to complete this model, thematerial is quite brittle, application of heat helps with the bending process, a hair dryer can be utilised.Please Note:Do not use products containing solvent on Depron material the Depron will disintegrate,do not use superglue.Test your products on one of the 300 x 300mm scrap pieces supplied. Broad felt tip pens or water based Acrylicpaints are suitable for colouring.A wide range of Lancaster markings and camouflage can be found in the following website.http://wp.scn.ru/en/ww2/b/555/9/0If you want realistic camouflage colours http://www.warbirdcolors.com/ can supply the correct BritishStandard paints. Paint can be applied by brush or airbrush.If you wish to mark any guide lines on Depron you should use a ball point pen with a light touch, or a fine pointfelt tip pen. Depron marks easily so any markings should be on the inside of the parts.Items being joined can be bonded with UHU Por adhesive, 5 min epoxy, or hot glue.Sewing pins or sellotape can be used to hold the pieces while they set, please note that sellotape whenremoved may leave a mark where it has removed the “bloom” of the depron, this will be noticeable whenmaking the first paint covering.A kit of parts is also supplied of plywood, wires for the servos, magnets for the mounting of the bomb baypanel, and some spare depron in case of breakages.Some trimming and shaping will be required.GB_Assembly_instructions_lancasterPage 1 of 6

Depron Parts KitPet-g partsThe engine nacelles can be partiallyassembled as shown in the first picture,and then when the glue is set, thebends required can be made and theresultant curves glued and held inposition with sellotape until set.When assembled, the nacelles shouldbe rounded at the corners, and ventholes cut at an angle to allow for motorcooling.Positioning of the support arches for the fuselage coversGB_Assembly_instructions_lancasterPage 2 of 6

A series of arches have been supplied,these can be glued in place on the frontand rear main frames they will give aguide for the fixing of the fuselage sidesections.Positioning of the aerofoil profiles and main and wing spars, and the dihedral.The wing and main spars should be spliced where they join.The wings should be assembled in two pieces separated at the centre, in order that the wings can beinserted into the fuselage. Cuts will have to be made in the aileron profiles, and the slot in thefuselage to accommodate the spars and also allow the laying of the wiring to the motors and servos.Fitting the wings will depend uponwhether or not you want to be able tomake the wings removable. In thisexample a connection has been madefrom styrene tube and round dowel.(Not included in the kit). These partsare easily available at hobby shops andsome hardware stores. If you intend tomake the wings fixed, each wingsection should be fully completed withthe wiring laid in for the motors andthe servos, and the upper surfacecovered. The upper profile will be cut into the fuselage and the wings set intothe fuselage.GB_Assembly_instructions_lancasterPage 3 of 6

Before you cover the upper wingsurfaces, ensure that you have laid inthe wiring for the motors and aileronservos. This will require cuttingpathways through the aerofoils andsmall holes in the lower wing.You should first chamfer the leadingand trailing edges of the wing sections,and then glue the upper covering alongthe leading edge, leave this to setbefore bending the covering and gluingit at the trailing edge.Laying in the wiring.If the wings are to be gluedpermanently in position they shouldnot be assembled into the fuselageuntil the upper wing covers are inplace.When the wings are covered and set, the ailerons can then be cut at the trailing edges.After shaping, the tail plane can now beinserted and glued into place, then thebalsa leading edge for the elevatorsshould be placed alongside the tailplane.After tapering the elevators, they canthen be glued in position as shown.The elevator servo, and servo armsshould now be installed, the wingsinserted and the rest of the RCequipment installed, and tested, thisshould all be done prior to fitting theupper and lower fuselage covers.GB_Assembly_instructions_lancasterPage 4 of 6

This is because when ready the profilewill be traced on the side panels andthe wings set into the side panels byabout 6mm (The width of the depron)This model was made with removablewings.Ready now to prepare the upper andlower fuselage coverings.To shape the upper and lower fuselagecovers a 45mm dia rolling pin was used,any similar rod or tube can be utilised.The Depron was bent and held inposition with sellotape. It was warmedup using a hair dryer and then it wasthen left overnight. Depron when left inthe same position for a reasonable timewill “set” and retain the shape.GB_Assembly_instructions_lancasterPage 5 of 6

The centre of gravity is 50mm from the leading edge of the wing, on the main spar.50mmC of GDo not forget that, unless you build inaccess panels, all of the RC equipmentmust be inserted before you cover thewings and fuselage. An access panel forbattery change should be made wherethe bomb bay would be situated.We hope that you have a lot of fun flying your own LancasterGB_Assembly_instructions_lancasterPage 6 of 6
